8.5.2 SFB Switch-on/off of the solid fuel boiler
Example: (system 1) under the status that solid fuel boiler is enabled,
When tank temperature T3 drops below the switch-on temperature of solid fuel boiler
(SFON), and temperature of solid fuel boiler (T5) is between its minimum and
maximum temperature( MIN 3 and MAX3)
，
then solid fuel boiler R2 is triggered; when
tank temperature T3 rises up to the switch-off temperature of solid fuel boiler (SFOF),
or when temperature of solid fuel boiler (T5
）
exceeds the scope of its “MIN3” and
“MAX3”, then solid fuel boiler is ceased.
Note:
The
value of “MIN3” should be minimum 1
o
C higher than value of “SFOF”, for
example, when “SFON” is 50
o
C, “SFOF” is 55
o
C, and then “MIN3” must be “56
o
C” at
